New spurious GMP failures caused by Debian upgrade

I upgraded the various Debian guest instances over the past week-end.
Now, some 64-bit debian guest systems send spurious SIGKILL to GMP
32-bit ABI test runs. I not been able to reproduce any of these
failures, nor really tried to understand the trigger conditions.
Because of this bug, we should expect "Table 1. Unexpected failures" at
https://gmplib.org/devel/tm/gmp/date.html to contain some garbage
entries until this (kernel?) bug is fixed.
